LONDON – The life sciences industry exhaled sharply and prepared to labor over the fine print in 1,246 pages of text after the EU and U.K. reported they had agreed a post-Brexit trade deal on Christmas Eve. The U.K. has said it will take a light touch, at least initially, with implementation of new border controls taking place in three stages up to July 30, 2021. The EU has not said what its approach will be.
